Abstract A method of preparing polymer beads from chloroform solutions of bulk polymer was developed. The technique involved solvent removal while the polymer solution was stirred in an aqueous dispersing medium. Bead size could be varied by adjusting the concentration of the suspending medium and the method was found to be applicable to chloroformsoluble, water‐insoluble polymers. Copolymers, low‐tack rubbers, and polyblends were also converted to bead form and, in the latter case, phase separation occurred. Furthermore, it was possible to encapsulate finely divided inorganic fillers within the polymer beads. © 1992 John Wiley & Sons, Inc.
